AIEIPARATUS FOR MAKING ICE.

Application filed September 19, 191

lle it known that we, Tnonas l3. lllAGIN- xis, a citizen of the UnitedStates, residing in the city of Chicago, county of Cook, and State ofIllinois, and Tiioims GAFFNRY, a citizen oi? the United States, residingin the city of St. Louis, State of Missouri, have invented certain newand useful improvements in Apparatus for Making" lee, of which thefollowing is a specification.

.This vinvention relates to apparatus for making ice, and moreparticularly to an apparatus capable of making clear ice fromundistilled water. v

Among the salient objects of the invention are to provide, in anapparatus of the character above referred to, an improved means forfurnishing air to a plurality of individual tanks for agitating thewater during freezing; to provide a construction in which the verticaltube which extends down into the water will be held from movement to a'position where there is danger of freezing the tube into the ice cake;to provide a simple and eflicient means by which the amount of airpassing to the vertical tubes is controlled; to utilize. the conduit,from which the vertically extending tube is suspended, as a means forholding the can in its assembled position in the frame; to provide aconstruction in which a plurality of the can units are all provided withair from a common, source and a minimum number of lateral pipes employedfor such purposes; to so mount the, vertical'tubes and their late allyextending conduits which carry them that these parts may be readily removed to permit the individual withdrawal of the cans from the frame incase the contents ofthe cans freeze unequally; to per mit of the use ofa single spring for resiliently holding two or more of the vertical tubesupports in assembled position; and in general to provide an improvedapparatus by which clear ice may be manufactured from undistilled Water.

ln the drawings Figure 1 is view, partly in section, showing two cans inposition in the frame. Fig. 2 is an enlarged fragmentary sectional viewshowing in de-- tail the assembled. position of the parts.

Referring in detail to the embodiment of our invention shown in thedrawings, the individual cans or receptacles are designated by thereference characters 1, 1, etc. At

its upper end, each of these cans is provided with a return bend flange2, preferably i'ornied to surround a reinforcing member 3. The lower endof this flange rests upon a shoulder el tormed in the cross bars 5. Asimilar shoulder (3 is provided in the longitudinally extending bars 7,the bars 5 and '7 forming a frame work by means of which the cans aresuspended in brine or other freezing medium.

The frame work above mentioned is so proportioned in relation to theindividual cans that when the latter are inserted in the frame work theflanged portions 2 will rest upon the shoulders 4 and 6 and are securedin this position in the following manner: Along one or more of thelongitudinally extending bars7 is positioned a conduit 8 leading from amain supply pipe 9, and at the intersection of one of the transversebars 5 with the longitudinally extending bar 7, the conduit 8 has a Tcoupling 10 from which extends a transverse conduit 11 terminating in ahollow head 12. At one of its sides, and preferably at both sides, thehead 12 is provided with lateral openings 13 and I l the size of theseopenings depending on the amount of air it is desired shall be carriedto the tubes 15 and 15" which extend downwardly into the cans 'l and l.The tubes 16 and 16 which connect the head 12 with the verticallyextending tubes 15 and 15, do not extend entirely across the cans butare threaded into a T coupling 18 from. the opposite end of which thereextends a solid bar or rod 17 having one end threaded into the coupling18, and

'its outer end 19 extending into a socliet 20 formed in the transversebar 5. lhis construction permits of a single transverse pipe 11furnishing air-to two or-more of the individual ice cans, and alsoavoids the necessit v of using an individual spring for each bar l7. Asclearly shown in Fig. 2

an axis, and is also longitudinally adjustable along such axes bypressing the end 19. against the abutment 24: and thus compressmg thespring 22. The conduits 8 and 11 are preferably housed Within a seriesof inverted channel shaped casings 27 and 28 which rest on top of therespective bars 5 and 7.

In use, the various indivdual icecans or units are filled with water andpositioned \vithinthe main frame. The tubes 15 and 15' are then insertedin place in the following manner: The end 19 is placed against theabutment Z-t and the latter pushed inward to compress the spring asufiicient distance to allow the end to be sprung into the seat 26 ofthe head 12. Air isthen forced from the main supply pipe 9 through theconduits 8, 11 and 16 and 16 to the individual vertical tubes 15 and 15and through a plurality of apertures 29 is discharged into the waterwhile the latter is freezing. Owing to the fact that the brine or otherfreezing medium is positioned exterior of the cans, the water at thecenter will be the last to freeze, The air forced into th water willtend to carry the gases out with the air and to draw the sedimenttoward'the center. In order to prevent the employment of the airconduits as a securing means for holding the individual ice cans inproper position in the frames.

V'Vhile we have shown and described a particular embodiment of ourinvention, We do not desire to limit it to any details of constructionexcept as specified in the following claims:

We claim as our invention:

1. In apparatus for making ice, the combination with a plurality ofindividu lly removable receptacles, of a frame for solid receptaclescomprising a plurality of inter secting bars, a supply pipe extendingalong the face of one of said intersecting bars, one end of said supplypipe having alead to a source of air under pressure, and said pipe atits opposite end being provided With a lateral seat, a transverselyextending eonduit baring an open end engaging said seat and an aperturedvertical tube depending from said conduit;

2. In apparatus for making ice, the combination with a plurality ofindividually removable receptacles, of a frame for said receptaclescomprising a plurality of intersecting bars, a supply pipe extendingalong one of said intersecting bars, one end of said supply pipe havin alead to a source of air under pressure, a c iambered head con neeted tothe opposite end of said supply pipe and being apertured upon oppositesides, transversely extending conduits pivotally engaging and in opencommumcatlonwith said chambered head, and an apertured vertical tubedepending from each of said conduits into one of said receptacles.

3. In apparatus for making ice, the combination with a plurality ofindividually removable receptacles, of a frame for said re eeptac'lescomprising a plurality of intersecting bars provided with shoulderportions forming seats for the receptacles, said receptacles ha ingFlanged portions engagingsaid seats, a supply pipe extending along theupper face of said intersecting bars, one end of, said supply pipehaving a lead to a sourceof air under pressure, a chainb'ered headconnected to the opposite end of said supply pipe, said chambered headbeing apertured upon opposite sides and having a tapered seatsurrounding said aperture, a transversely extendingconduit having atapered end engaging said seat, an apertured vertical tube dependingfrom said conduit into the said receptacle, a member forming acontinuation of said transverse conduit and a seat in one of theintersecting bars for receiving the free end of said member to permitthe engagement and disengagement of the conduit With said head when thecan is in position'in said frame.
